A simple Node.js sample pilet feed service for use with Piral. If you don't want to play around with a feed service locally then use the (free) community edition of the official Piral Feed Service. Alternatively, if you are interested in more beef such as running the official Piral Feed Service in your environment or accessing premium features in the online edition then have a look at Piral Cloud website.

Getting Started

For running this sample locally all you need to do is running:

npm i && npm start

Remark: This sample requires Node.js and NPM. The used port is 9000, which could be re-configured easily (e.g., via an environment variable PORT).

Auth Keys

For publishing a Pilet a handful premade keys have been added (file: src/auth/keys.ts):

Either change the file when using this service in any non-local infrastructure or set the environment variable PILET_API_KEYS with comma separated values (e.g., A,B,C uses three keys A, B, and C instead).

Pilet Database

For this simple sample everything is kept in memory. If you want to change this behavior to store the pilets also in a database / some storage you will need to modify the src/db/index.ts file.

Remark: The file has been prepared in such a sense that all exposed functions already return promises.

Reported URL

For the pilets the reported URL is http://localhost/... unless changed via src/constants.ts. For simplicity, a resolution algorithm based on standard environment variables is already active.

Variable Meaning
WEBSITE_HOSTNAME The name of the host, e.g., localhost
PORT The port, otherwise falling back to 9000
HTTPS Is HTTPS active, otherwise falling back to HTTP
PILETS_SNAPSHOT Defines the path of the database snapshot directory
HTTP_X_FORWARDED_PROTO The used protocol (e.g., http), otherwise falling back to the HTTPS setting

Snapshot

By default, the service creates a directory called pilets in the current working directory. If you don't want this (i.e., no snapshot should be created) then set the PILETS_SNAPSHOT environment variable to an empty string i.e., PILETS_SNAPSHOT="". Otherwise, if you want to use another directory, set the variable to a directory, e.g., PILETS_SNAPSHOT=/tmp/pilets.

Usage via NPM

Alternatively, if you want to use the service only locally to play around you can also install and run the package via NPM:

npx sample-pilet-service

You could also install it globally:

npm i sample-pilet-service -g

This will enable a new command sample-pilet-service to be invoked on the command line shell.
